Jack parked his car at the carpark from 4.31 p.m to 11 p.m. How much did he pay for his parking?
From 4.31 p.m. to 5.31 p.m.: 1 h
From 5.31 p.m. to 11 p.m.: 5 h 29 min
1 h = 60 min
5 h 29 min = 5 x 60 + 29 = 329 min
Number of sets of addtional 30 min in 6 h 29 min
= 329 ÷ 30
= 10 r 29
Number of sets of 30 min that Jack had to pay for
= 10 + 1
= 11
Amount that Jack had to pay for 11 sets of additional 30 min
= 11 x 1.30
= $14.30
Total amount that Jack had to pay for his parking
= 2.60 + 14.30
= $16.90
Answer(s): $16.90
